Description

  The present invention relates to a transport installation apparatus, and more particularly to an improvement of a transport installation apparatus suitable for use in transporting a transported object such as a heavy object and subsequent installation.

  There have been various proposals for a transport installation device suitable for transporting a transported object such as a heavy object and subsequent installation. For example, in the heavy goods moving installation work cart disclosed in Patent Document 1, The frame is composed of a frame support with casters and a horizontal beam, and at least two pairs of chain block support are provided on a pair of parallel horizontal beams, and a load is placed between the chain block support. A horizontal dedicated beam material for installation is detachably mounted, and a chain block is provided at the upper end of the support for the chain block, and the chain block lifts and lowers the loop-like chain that suspends the conveyed item.

  Therefore, according to this working carriage, the transported object is placed on the dedicated beam material, moved to the installation location together with the frame by using a caster, and transported on the dedicated beam material and looped around the loop. It is possible to lift the object by pulling up the chain by operating the chain block, pull out the dedicated beam material from this position, then lower the chain by operating the chain block to lower the transferred object, and then set the transferred object at the installation position. It becomes possible.

Japanese Patent Laid-Open No. 08-282502

  However, the work cart disclosed in the above-mentioned Patent Document 1 has a problem that it must be performed after the level adjustment and the verticality adjustment of the conveyed product lowered to the installation position are lowered to the installation position.

  In other words, in the work carriage described above, when the conveyed product is lowered to the installation position, the conveyed item is suspended with a chain.When the chain is suspended with this chain, the level and verticality of the conveyed item are not adjusted. The level and verticality of the transported goods that have been lowered to the installation position will not be adjusted.

  Therefore, after the conveyed product is lowered to the installation position by the above-described work carriage, or when the conveyed item is lowered to the installation position, the operator can adjust the adjustment member such as a wedge while hanging the conveyed item with a simple lift. As a result, the level of the conveyed product is adjusted or the verticality is adjusted using this method, which causes a disadvantage in that it takes time to install the conveyed product.

  The present invention was devised in view of such a current situation, and facilitates level adjustment and verticality adjustment of the conveyed product during the installation operation at the installation position of the conveyed product, and the time required for installation of the conveyed product. It is an object of the present invention to provide a transport installation device that can be shortened.

  In order to achieve the above-described object, the configuration of the transport installation apparatus according to the present invention includes a base portion on which a transported article is placed, a holding portion that holds both ends of the base portion, and a caster that is connected to the holding portion. And a height adjusting mechanism that is provided between the holding part and the caster and adjusts the height position of the conveyed product placed on the base part.

  Therefore, in the present invention, the height adjusting mechanism is provided between the holding portion and the caster, and the height position of the conveyed product placed on the base portion can be adjusted. Thereby, when the conveyed product placed on the platform is installed at a predetermined installation position, level adjustment and verticality adjustment of the conveyed product can be easily practiced at the installation position.

  As a result, according to the present invention, the level adjustment and the verticality adjustment of the conveyed product are facilitated during the installation work at the installation position of the conveyed product, and the time required for the installation work of the conveyed product compared to the conventional work cart. Enable shortening.

It is a front view which shows the utilization state example of the conveyance installation apparatus by this invention. It is a side view which shows the utilization state example of the conveyance installation apparatus by this invention. It is an enlarged side view which shows the utilization state example of the conveyance installation apparatus by this invention. It is an enlarged plan view which shows the utilization state example of the conveyance installation apparatus by this invention.

  The present invention will be described below based on the illustrated embodiments. As shown in the figure, the transport installation apparatus according to the present invention is used for transporting a transported object, which is a heavy object, to an installation location and for installing a transported object at an installation position.

  At this time, the transported object is a platform door unit Y that provides a platform door as a security facility on the platform P (see FIGS. 1 and 2), but other gates and door fences that function in the same manner as the platform door are provided. It may be a gate unit or a door fence unit to be provided, and may further be, for example, an acoustic reflector provided to be movable on the stage.

  That is, in the illustrated embodiment, the transport installation apparatus enables the work of transporting the home door unit Y assembled at a factory or the like to the installation place of the platform P, and the subsequent home door unit Y is transferred to the platform P. It enables the work to be lowered to the installation position. The home door unit Y lowered to the installation position is fixed to the platform P, and a platform door as a security facility is provided on the platform P.

  Although not shown in detail, the home door unit Y is, as shown in FIGS. 1 and 2, a box B fixed in a fixed state at the installation position of the platform P, and a box B accommodated in the box B and the box It has the door body D formed in the panel shape which appears and disappears in the horizontal direction seen from the front side in FIG.

  Incidentally, the box B has a frame F and an exterior body C that is detachably held by the frame F and visually blocks the frame F and the door body D that is stored inside the frame F. .

  At this time, since the framework F is fixed in a fixed state at the installation position of the platform P, it is formed in a so-called rigid body so as to have a predetermined self-supporting property, and can hold the door body D and the exterior body C. To. In particular, from the viewpoint of enabling the use of the transport installation apparatus according to the present invention, the framework F has a lower girder member F1 extending in the axial direction which is the left-right direction in FIG.

  Therefore, in this box B, the lower girder member F1 in the framework F is carried on the pedestal L, that is, the pedestal 3, by being supported on the pedestal 3 in the gantry L described later.

  Further, in this home door unit Y, an arbitrary configuration can be selected for the moving mechanism of the door body D with respect to the box body B. Although not shown, for example, a gear in a drive source held by the box body B is a door. The door body D is configured to mesh with an endless timing belt held in a fixed state by the body D, and the gear rotates and the timing belt rotates.

  Incidentally, when the platform door unit Y is transported to the installation location by the gantry L and until the platform door unit Y is lowered from the gantry L and installed at the installation position, the exterior body C is removed from the framework F, and the exterior The damage to the body C is avoided, and the work of transporting and installing the platform door unit Y is not hindered.

  Note that after the home door unit Y is installed at the installation position, for example, when performing maintenance on the moving mechanism of the door body D, the exterior body C is partially or completely removed from the framework F.

  Although the installation location of the platform door unit Y is not shown in detail, it is the platform P at the railway station, and the installation location is closer to the platform end P1 (see FIG. 2) on the track side of the platform P. .

  That is, when providing a platform door on the platform P at a railway station, a space is provided between the box B in the platform door unit Y and the platform end P1 in the platform P so that one person can stand up. The platform door is provided in a state of approaching the platform end P1 of the platform P.

  Therefore, in the transport installation device according to the present invention, as will be described in detail later, when the platform door unit Y is lowered to the installation position, the platform P is left at a limited installation position near the platform end P1 on the track side. We consider so that it can be lowered.

  In addition, in the place shown in FIG.1, FIG2 and FIG.3, the skeleton F has shown the state before installation to the platform P. FIG. Therefore, although the lower end of the column member F2 for connecting the lower girder member F1 is lifted from the upper end of the platform P, it appears between the lower end of the framework F and the upper end of the platform P after being installed on the platform P. The space to be filled is partially or entirely filled with appropriate means.

  By the way, the conveyance installation apparatus by this invention has the mount frame L as shown in FIG. 1 and FIG. 2, and this mount frame L is made into a pair positioned before and after the advancing direction used as the left-right direction in FIG. .

  At this time, the front and rear mounts L are separated from each other as shown in the drawing. However, from the point of the present invention, the front and rear mounts L may be connected to each other by appropriate connecting means. When the front and rear mounts L are separated, it is advantageous in handling and carrying the mount L.

  The gantry L includes a holding part 1, a caster 2, and a pedestal part 3. When the axial direction of the gantry L is a direction crossing the traveling direction which is the left-right direction in FIG. 2, the holding portions 1 are provided at both ends in the axial direction, and the casters 2 are held by the holding portions 1. This makes it possible to move the gantry L.

  At this time, the gantry L has a height adjustment mechanism, and the height adjustment mechanism is fixed to the caster 2 and screwed to the holding part 1 at one end as a lower end in FIG. A threaded shaft 24, and an operating handle 25 that is provided at the other end of the threaded shaft 24 that is the upper end in FIG. 3 and that rotates the threaded shaft 24 relative to the holding unit 1. It has.

  Therefore, in this height adjustment mechanism, when adjusting the height of the home door unit Y, the screw shaft 24 can be rotated by rotating the operation handle 25 as an operation portion. Thus, the holding portion 1 to which the screw shaft 24 is screwed is moved up and down.

  Moreover, the base part 3 is a height position lower than the upper end of the holding | maintenance part 1, Comprising: It is provided between a pair of holding | maintenance parts 1, and the platform door unit Y is mounted.

  At this time, since the base part 3 in the gantry L lowers the height position of the upper end as compared with the upper end of the holding part 1, the position of the center of gravity of the gantry L is lowered and the home door placed on the base part 3. The position of the center of gravity of the unit Y can be lowered, and the home door unit Y that exhibits a so-called standing state as shown in FIGS. 1 and 2 can be placed in a stable state.

  On the other hand, the holding part 1 and the base part 3 in the gantry L are formed of, for example, a steel material so as to have mechanical strength that does not bend when the platform door unit Y is transported.

  At this time, in order to make the upper end flat in the base part 3, the cross section in the direction crossing the axial direction is made into a horizontally long rectangle. Thereby, it is easy to obtain stability in the platform door unit Y placed on the platform 3.

  Further, as described above, the holding portion 1 has a height adjustment mechanism and is formed so as to enable adjustment of the height of the connection position of the casters 2. However, the lock nut 21 ( In order to improve the contact property to the holding portion 1 of FIG. 3), the upper end is formed flat, that is, formed in a rectangular shape.

  From this, the holding part 1 and the base part 3 in the gantry L are formed of steel square pipes, and the rigidity with respect to bending and twisting is increased, and the same width from the viewpoint of improving the appearance. It is good to form so that it may have a dimension (refer FIG. 4).

  In the above-described gantry L, a connecting portion 4 (see FIG. 3) in which an end portion on the base portion 3 side in the holding portion 1 and an end portion on the holding portion 1 side in the base portion 3 are arranged in the vertical direction. At this time, the upper end portion of the connecting portion 4 is connected to the end portion of the holding portion 1 in a fixed state, whereas the lower end portion of the connecting portion 4 is detachably attached to the end portion of the base portion 3. Connected.

  Accordingly, for example, after the platform door L is installed at a predetermined installation position by the gantry L, the gantry L is not moved when the gantry L is removed. By separating, so-called disassembly can be removed to facilitate the removal work.

  Moreover, in this case, in the present invention, since the holding portion 1 has the caster 2 and also has the connecting portion 4, the holding portion 1 is separated from the base portion 3, and the gantry L is the home door unit. When it is removed from below Y, it becomes possible to remove the so-called bar-like base 3 by pulling it out below the platform door unit Y in a direction crossing the advancing direction of the gantry L. Improve workability.

  In addition, about the means which implement | achieves the separable connection of the base part 3 and the connection part 4, arbitrary structures may be selected, but in the illustration, from the connection structure using the pin 41 (refer FIG. 4). Thus, when the pin 41 is extracted from the connecting portion between the base portion 3 and the connecting portion 4, both can be separated. The pin 41 is connected to the holding portion 1 with a rope member 42 (see FIG. 3) for preventing loss.

  By the way, as shown in the figure, the gantry L is formed by detachably connecting the holding unit 1 and the pedestal unit 3 by the connecting unit 4. However, considering the function of the gantry L, the gantry L is suitable for the gantry L. Thus, the holding unit 1 and the base unit 3 may be integrally connected.

  That is, in the above description, the connecting portion 4 provided integrally with the holding portion 1 is detachably connected to the base portion 3, but the connecting portion 4 is also provided integrally with the base portion 3. It may be.

  In this case, since the holding part 1 and the base part 3 are integrated via the connecting part 4, for example, as described above, the holding part 1 and the base part 3 are detachable via the connecting part 4. Thus, it is not necessary to worry about the loss of the so-called member which is the holding part 1 or the base part 3, which is advantageous in facilitating the storage and transportation of the gantry L.

  Moreover, since the holding | maintenance part 1 and the base part 3 are integrally formed via the connection part 4, compared with the case where the holding | maintenance part 1 and the base part 3 are formed detachably via the connection part 4. In forming the gantry L, there are advantages that the number of members is reduced and the gantry L can be formed firmly.

  Incidentally, when the holding part 1 and the base part 3 are integrally formed, the base L is positioned below the home door unit Y, or when the base L is removed from below the home door unit Y, the base L is placed on the base L. What is necessary is just to make it move to the advancing direction.

  On the other hand, as described above, the caster 2 is provided so as to freely adjust the height of the connection position with respect to the holding portion 1. Therefore, when the caster 2 increases the connection position with respect to the holding portion 1, The height position of the pedestal 3 can be increased. For example, when the platform door unit Y placed on the pedestal 3 is transported, it is possible to avoid a problem that the bottom surface of the pedestal 3 comes into contact with the ground or the like, thereby improving transportability.

  Moreover, when the caster 2 lowers the connection position with respect to the holding part 1, the height position of the base part 3 can be lowered in the gantry L. For example, the work of placing the home door unit Y on the base part 3, and While making it easy to lower the platform door unit Y from the platform 3, it becomes possible to lower the position of the center of gravity of the platform 3 and the position of the center of gravity of the platform door unit Y placed on the platform 3, This makes it easy to obtain stability when the home door unit Y is transported.

  In the pair of mounts L, the casters 2 of the holding portions 1 which are a total of four locations can freely adjust the height of the connecting position in each holding portion 1, so that the selected holding portion 1 can be raised or lowered via the casters 2. By adjusting, the level adjustment and the verticality adjustment in the platform door unit Y that is lowered from the base 3 to the installation position are enabled.

  As shown in FIG. 3, the caster 2 includes a wheel 22, a bracket 23 that pivotally supports the wheel 22, a lower end rotatably connected to the upper end of the bracket 23, and a screw shaft 24. And an operation handle 25 serving as an operation unit coupled to the upper end of the screw shaft 24.

  The screw shaft 24 is eccentric in the horizontal direction with respect to the axle position of the wheel 22 pivotally supported by the bracket 23 (see FIG. 1) and the lock nut 21 (see FIG. 3). The holding part 1 is screwed under the screwing.

  Incidentally, one end portion of the screw shaft 24 which is the lower end portion in FIG. 3 is rotatably connected to the upper end of the bracket 23 in the caster 2, so that even if the one end portion is not screwed. good.

  The holding portion 1 has a nut 11 fixed to the lower end, and this nut 11 screws the screw shaft 24, so that the screw shaft 24 is rotated with respect to the holding portion 1 in a fixed state. Then, the screw shaft 24 moves up and down with respect to the holding unit 1.

  Therefore, in this caster 2, the bracket 23 having the wheels 22 is rotatably connected to the lower end portion of the screw shaft 24 that is screwed to the holding portion 1. Enable.

  In the caster 2, the screw shaft 24 is eccentric with respect to the wheel 22 pivotally supported by the bracket 23, so that when the operation handle 25 is rotated, the screw shaft 24 is rotated. In addition, the wheels 22 do not move together, that is, the wheels 22 do not rotate in the horizontal direction, and the screw shaft 24 can be moved up and down with respect to the holding portion 1.

  Note that the lock nut 21 prevents the screw shaft 24 from rotating with respect to the holding portion 1 while the lock nut 21 is tightened, for example, while the home door unit Y is being transported. May be arbitrarily configured. As shown in the figure, the lock nut 21 has an operation lever 21a (see FIGS. 1 and 4). The lock nut 21 can be rotated by the operation lever 21a, and a tool such as a spanner can be used. It is designed so that it can be rotated without any effort.

  Although the operation handle 25 is a round handle with a grip (not shown) in the drawing, it can be a bar handle, for example, in view of its function.

  From the above, the height adjustment mechanism has a screw shaft 24 that fixes one end portion to the caster 3 and an operation handle 25 that is an operation portion provided at the other end portion of the screw shaft 24. The height position of the conveyed product can be adjusted with a simple configuration.

  By the way, about the base part 3 in the above-mentioned mount L, the place where the base part 3 is left-right direction in FIG. It is made larger than the width dimension in alignment with the axial direction of the base part 3.

In addition, the base unit 3 includes a connecting mechanism 5 that connects the home door unit Y placed on the base unit 3 to the base unit 3.

  Since the length of the platform 3 is larger than the width of the platform door unit Y mounted on the platform 3, even when the platform door unit Y has various widths, enable.

  Moreover, since the base part 3 has the connection mechanism 5, the connection mechanism 5 can integrally connect the platform door unit Y placed on the base part 3 to the base part 3. When transporting the home door unit Y, it is possible to realize stable transport by pushing the home door unit Y. For example, when the operator takes a deep forward tilting posture, the platform 3, that is, the platform L is directly pressed. Compared to the case, the physical burden on the operator is reduced.

  By the way, the connecting mechanism 5 has a pair of sandwiching bodies 51 that are provided on the base 3 and sandwich the home door unit Y from the width direction of the home door unit Y, and one of the pair of sandwiching bodies 51. One or both of them are provided movably on the base 3 along the axial direction of the base 3.

  As a result, the home door unit Y placed on the pedestal 3 can be shifted to one side in the axial direction of the pedestal 3, for example, on the right holding part 1 side in the position shown in FIG. 3. Thus, the home door unit Y can be lowered to a limited installation position below the offset position.

  At this time, as shown in FIG. 2 and FIG. 3, the right side coupling mechanism 5 in the figure is provided so as to face the left side coupling mechanism 5 in the figure, but instead, in FIG. 3 and FIG. As shown by a one-dot chain line diagram, the right coupling mechanism 5 may be provided so as to face the same direction as the left coupling mechanism 5.

  In this case, it is possible to further offset the home door unit Y on the pedestal 3 so as to be adjacent to the holding unit 1 on the right side of the pedestal unit 3. It is possible to lower the home door unit Y to a limited installation position below.

  The sandwiching body 51 is shown in the figure, and a main body 51a disposed in a direction crossing the axis of the pedestal 3, and both ends of the main body 51a as upper and lower ends in FIG. And a collar 51c extending in the left-right direction in FIG. 3 and FIG. 4 from the standing part 51b.

  And in this clamping body 51, when the main-body part 51a is connected with the receiving member 52 which opposes on both sides of the base part 3, it shall be fixedly connected with the base part 3, and it will mutually oppose at this time Assume that the lower girder member F1 as a pair of the frame F constituting the home door unit Y with the upright portion 51b interposed therebetween is clamped, and the flange portion 51c prevents the lower girder member F1 from rising.

  At this time, the main body 51 a of the sandwiching body 51 and the receiving member 52 facing the main body 51 a are connected by a bolt 53 penetrating from the receiving member 52 to the main body 51 a, and are screwed to the bolt 53. Further, the operation nut 54 can be turned and tightened and released.

  Therefore, as described above, in the coupling mechanism 5 having the above-described sandwiching body 51, when the sandwiching body 51 is moved along the axial direction of the base portion 3 together with the receiving member 52, the platform doors having different width dimensions are used. The unit Y can be clamped. Similarly, as described above, for example, as shown in FIG. 3, the home door unit Y offset to the right holding unit 1 side can be integrally connected to the base unit 3, The rear home door unit Y can be lowered to a limited installation position below the position offset to the right holding unit 1 side.

  Incidentally, the above-described sandwiching body 51 has a flange 51c, and prevents the lower girder member F1 from being lifted by the flange 51c. However, the platform door unit Y is, for example, a heavy object exceeding 200 kg. In view of this, it can be said that the flange 51c is not necessary.

  That is, since the platform door unit Y placed on the base 3 has a weight exceeding 200 kg, the frictional resistance with the base 3 will be increased, so long as there is no external force action exceeding this. This is because there is no movement on the base part 3, and therefore there is no need to have a configuration for preventing the lower girder member F1 from rising.

  As described above, in the transport installation apparatus according to the present invention, the pair of front and rear bases L in the advancing direction has the casters 2, so that the bases L can be run by the casters 2, and the casters 2 Makes it possible to adjust the height position with respect to the gantry L. By lowering the height position of the gantry L, the position of the center of gravity of the gantry L can be lowered, and the work of placing the home door unit Y on the gantry L and the gantry The work of unloading heavy objects from L is facilitated.

  And since the caster 2 can adjust the height position with respect to the gantry L and the center of gravity of the gantry L can be lowered, the center of gravity of the home door unit Y placed on the gantry L can also be lowered. It makes it easier to obtain stability during transportation.

  And in a pair of mount L, since the holding part 1 used as a total of four places each adjusts the height position via the caster 2, the selected holding part 1 can be adjusted to the installation position by adjusting the height. It is possible to adjust the level and the verticality of the platform door unit Y to be lowered.

  In addition, since the frame L has a length dimension in the axial direction larger than the width dimension of the platform door unit Y on which the platform L is placed, the platform L has a connecting mechanism 5 that couples the platform door unit Y to the platform L. The home door unit Y divided into sections can be placed, and the home door unit Y placed by the connecting mechanism 5 can be integrally connected to the gantry L.

  Further, since one or both of the pair of sandwiching bodies 51 that sandwich the platform door unit Y between the coupling mechanism 5 provided on the platform 3 is movable, the platform door unit placed on the platform L Y can be shifted to either side, and the home door unit Y can be lowered to a limited installation position below the offset position.

  In the transport installation apparatus according to the present invention formed as described above, the home door unit Y can be transported and installed after transport by operating as follows. In Y, the exterior body C is removed in order to avoid damage to the exterior body C in the box B.

  A direction in which the bases 3 constituting the pair of gantry L in the front and rear are located below the home door unit Y and cross the traveling direction of the gantry L below the framework F in the home door unit Y from which the exterior body C is removed. The platform door unit Y is integrally connected to the platform 3 inserted below the platform door unit Y by the coupling mechanism 5.

  The holding part 1 is connected to both ends of the base part 3 to which the home door unit Y is integrally connected by the connecting mechanism 5 via the connecting part 4, and the state in which the holding part 1 is connected to the base part 3 is established. This is ensured by inserting the pin 41.

  From this posture, the holding part 1 is raised by the rotation of the screw shaft 24 in the caster 2 to avoid the base part 3 from interfering with the ground or the like, and then the home door unit Y is pushed and conveyed to the installation place.

  The home door unit Y transported to the installation location can be adjusted in level and verticality in the home door unit Y by rotating the screw shafts 24 in the casters 2 in a total of four locations to raise and lower each holding portion 1. Made.

  The home door unit Y for which the level adjustment and the verticality adjustment have been completed is lowered to a predetermined installation position on the platform P by the lowering of the holding unit 1 due to the rotation of the screw shaft 24 in the caster 2 in this state.

  The home door unit Y lowered to a predetermined installation position on the platform P is fixed and installed on the platform P by a so-called fixing operation, but level adjustment and verticality adjustment in the home door unit Y are practiced in advance. Therefore, installation work becomes easy.

  After the installation work of the home door unit Y to a predetermined position is completed, the home door unit Y and the gantry L can be separated by so-called release of the connecting mechanism 5.

  In the gantry L separated from the home door unit Y, the holding portion 1 is removed from both ends of the pedestal portion 3 so that the holding portion 1 and the pedestal portion 3 are separated. The unit Y is extracted from below.

  The base part 3 and the holding part 1 with casters 2 taken out from below the home door unit Y are used again.

  As a result, according to the transport installation apparatus of the present invention, while allowing the home door unit Y to be transported to a predetermined installation location, in particular, it is possible to adjust the level and the verticality of the home door unit Y. At the same time, the work time in the installation work of the platform door unit Y can be shortened as compared with the conventional work cart.

  As described above, the installation location of the platform door unit Y is the platform P, in particular, the platform P at the railway station. In view of the function of this platform, for example, Furthermore, it may be a corridor that leads to an entrance or stairs that require entry restrictions.

  In addition, as described above, the height adjusting mechanism has the screw shaft 24 that is connected to the caster 2 at one end and is rotatable with respect to the holding portion 1, and rotates the screw shaft 24. Thus, the holding unit 1 is moved up and down. However, in consideration of the function of the height adjustment mechanism, other configurations, for example, the screw shaft 24 is abolished and the caster 2 and the holding unit 1 are disposed. A jack device that extends and contracts in the vertical direction may be provided.

  And in the place mentioned above, the support body 51 which comprises the connection mechanism 5 is handled with the base part 3 while being provided in the base part 3 in the base L so that it can be separated, that is, it constitutes a part of the base L. However, as described above, in consideration of installing the platform door unit Y as a transported object at a predetermined installation position, when the platform door unit Y is installed, the support 51 is separated from the gantry L and placed on the platform P. It may be used as a mounting bracket to be connected.
